: GRAIN-TREATING MACHINE.

Specification of Letters Patent.

Patented Oct. 4-, 1921.

Application filed February" 6, 1920. Serial No. 356,724.

To all whom it may concern Be it known that I, HENRY LEPAK, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Grain- Treating Machines, of which the following is a specification. V I v Grain stored in damp places or while containing moisture, deteriorates from many causes, smut being the principal disease. The present invention provides a machine which enables the grain to be readily and successfully treated to remedy the trouble.

The drawings illustrate a preferred embodiment of my invention. However, it is to be understood that in adapting the same to meet various conditions, various changes in the form, proportions and minor details of construction may be resorted .to without departing from the nature of the as claimed hereinafter.

Referring to the drawings hereto at tached: v I V Figure 1 is a side viewof a machine emboo lying the invention, the dotted lines indiinvention eating an adjusted position of. the type which receives the grain to be treated,

Fig. 2 is a vertical longitudinal section of a machine, the upper and lower portions of the supporting frame work being broken away, V

Fig. 4 is a detail perspective VlBW of the dipper,

Fig. 6 is a detail perspective View of the p Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

The machine embodies in its organization,

a supporting frame work, a pan for containing the solution, a dipper for receiving the grain to be treated and operating mecha-- nism for actuating the dipper whereby the grain may be lifted from the treating bath and discharged.

The frame work comprises side supports, longitudinal bars and connected cross members. The side supports embody bars 1 which are upwardly converged and have their upper ends secured to a cross piece 2, the latter projecting at one end beyond a side support as indicated most clearly in Fig. 8, to receive a guide pulley 3. Longitudinal bars 4 connect the members of the respective side supports and terminate in handles 5. Suitable cross pieces 6 connect the longitudinal bars 4 and in conjunction with the cross piece 2 brace and strengthen the frame work. Standards 7 are secured to corresponding end portions of the longitudinal bars 4: and support a transverse rod 8.

A pan 9 is supported upon corresponding end portions of the longitudinal bars a and is adapted to receive the solution for treating the grain. The pan 9 may be of any construction and is placed upon certain cross pieces 6. A plate 10 is disposed at one side of the pan 9 and is supported at one end upon a side of thepan. The plate 10 is supported at its opposite end by means of the transverse rod 8. It is to be understood that the plate 10 may be of any construction and supported in any convenient way. The plate 10 is provided at its longitudinal ends with upwardly extended flanges to prevent lateral escape ofthe solution received upon the plate and conducted thereby back to the pan 9. The plate 10 inclined slightly to the horizontal being lowest at the end adj acent the pan 9 and highest at the end distant therefrom. As a result, drippings received upon the plate 10 arev conducted thereby, back to the pan 9.

A dipper like structure is disposed above the pan 9 and return plate 10 and comprises a receptacle 11 and an extension 12. The receptacle 11 is of a size to be received within the pan 9 and is adapted to contain the grain to be treated. The extension 12 is disposed above the plate 10 and projects some dis tance in the rear thereof so as to discharge the grain'into a suitable receiver. The receptacle 11 and the extension 12 are closed at opposite sides and the bottom of each is of screen formation whereby to retain the grain but provide an escape for the solution. The bottom of the dipper may be of any suitable screen material generally employed in the art of milling and said material may be suitably reinforced and braced by cross pieces 13. The inclosing side members are also to receive the screen material which rests thereon. The ,dipper is mounted so that the part 11 thereof may be received from or lowered into the pan 9. In the preferred construction, the dipper is preferably supported at its delivery end upon the transverse rod 8, the parts bein of such relative arrangement that when tie dipper is lowered the part 11 enters the pan 9. When the dipper is elevated itassumes an inclined position and when fully elevated the grain contained in the receptacle 11 will pass therefrom onto the extension 12 and discharge therefrom by reason of the inclination. Any suitable means may be provided for raising and lowering the dipper and as shown an operating lever 14 is mounted upon an end portion of the transverse rod 8 and a cord or like part '15 is con nected atone end thereto and passes over the guide pulley 3 and a like guidepulley 16 disposed centrally of the cross piece 2 and has its opposite end connected to a cross piece 17 applied tothe' dipper, When the free end of the lever 14: is elevated, the dipper is at its lowest position, withthe lower portion of the receptacle 11 immersed in the solution contained in the pan 9. When the :front endof the lever 14 is depressed, the

dipper is elevated so as-to discharge the v grain after the same has been subjected to the solution or bath contained in the pan 9.

In theoperation of the machine, the grain to be treated is placed in the receptacle 11 and the pan 9 is supplied with a solution according to the nature of the disease to be treated. 35

Usually a solution of formaldehyde is supplied to the pan 9 and it is to be understood that the grain to betreated is supplied to the receptacle portion 11 of the dip er in such quantity as to insure its com lete immerslon 1n the SOllltlOlL; After t e gram has been treated for the requisite'length of I time it is discharged from the dipper by manipulation of the lever 14' in the manner herein stated. This effects a tilting of the dipper to such an angle as to cause the grain to pass from the receptacle 11 onto the extension 12 and over the latter into a suitable vessel placed for its reception. 'VVhen the dipper is elevated, the solutlon drained from the grain contained in the receptacle 11 passes back into the pan 9 and any drippings discharged from the grain in its passage over the screen bottom of the extension 12 is received on the plate 10 and returned upon said pan 9 as will be readily unand laterally of the frame for discharge purposes, said means embodying a. receptacle movable to dip into said solution receptacle and an extension forming a dischargespout forthe dipper receptacle and perforated to drain upon said plate substantially throughout it length.

a supporting frame work, a solution receptacle supported on one side of the frame,

a shaft supported on the opposite side of the frame and above the level of the said recep- V tac1e,a drain plate spaced between the shaft and receptacle and discharging into the latter, a dipper of perforated material'arranged lengthwise over and along the said receptacle and plate and adapted to. drain 2. A grain treatingapparatus comprising upon the lattersubstantially throughout its length, said dipper embodying an extension movable crosswise of the said shaftiwhen the dipper is-elevatedand a receptacle, at the other end of the extension movable to dip-into said solution receptacle whenthe dipper is lowered, and means forraising and lowering the said" dipper.

lution receptacle connected therewith into which said plate discharges and a dipper formed of perforated material having a re-o cepta'cle of limited capacity movable to dip into said solution receptacle and also having a longltudlnal extension disposed above and along said drain plate and adapted to drain pan substantially throughout its length. l V In testimony whereof I affix my signature in presence of two witnesses. 1
